    Is it any helpful to increase CPU priority level for specific programs?

    Hi Friends,

    Is it any helpful to increase CPU priority level for certain apps or programs? Does it really make any difference in the performance?

    Not really for the majority of desktop systems. Provided you're not trying to do something like gaming while a video is encoding in the background with the same priority level, the scheduler should do a good enough job by itself. Many applications already request sane priority levels e.g. BelowNormal for some video encoders.

    You're not going to improve performance of the only app running on a system by changing its priority level, that's akin to the 'optimisations' recommended by people who don't really know what they're suggesting e.g. disabling indexing on SSDs, changing number of cores assigned to boot in msconfig, etc. At best they achieve nothing, at worst they actually cause harm. Yet they're still echoed around the web as sane advice...

    A word of advice - never set *anything* manually to Realtime priority unless you *really* know what you're doing - setting a demanding load to Realtime has the potential to lock up the system and could be especially problematic if it's scheduled to launch at boot!
